RCBS (is part of ATKs Civil Ammunition Systems Group) like many companies that manufacture ammunition are super busy working extra shifts, etcetra...
Your best bet is to email them firstname.lastname@example.org and they should get back to you with an answer in 24 to 48 business hours, be sure to give them your full name and address with your question or problem to solve and the best way to get a hold of you if needed. Until the ObamaNation settles down, long delays and long hold times are going to be a problem.
Otherwise, call RCBS (1-800-533-5000) "As Early As Possible" Monday thru Thursday (closed on Fridays, Saturdays & Sundays) at least to the public. Also, remember their hours are Pacific Standard Time being in California.
Getting replacement parts and such has been slow and time consuming by phone, but emails go smoothly, and you might get a package to your door in 2 or 3 days without even getting a call back!! Now that is what I call "Service"
